My research interests are focused on two areas in the socioecology of subsistence: one examining patterns in individual decision-making, the other focused on examining the effects of aggregate decisions on habitat structure, and how those decisions feed back over the long term to influence individual subsistence strategies.  At the micro scale, I focus on gendered strategies of social and economic production, especially as these relate to altruism and public goods provisioning in strategies of competition for prestige.  I'm particularly interested in how signaling theory might shed light on “show-off” types of subsistence activities, especially those that offer high opportunity costs with little apparent economic payoff.  Signaling theory may also help to understand the costliness that arises from public goods provisioning, and the pathways of benefit to political strategizers.  At the macro level, I’m interested in the costs and benefits of indigenous conservation and land management, especially with regard to how subsistence decision-making by Martu foragers in Australia’s Western Desert affects habitat heterogeneity and biodiversity through the influence of anthropogenic fire.
